The Schedule referred to in these Letters Patent and making part of the same.

The object of this invention is so to improve the construction of machines for making twine, cord, Sto., that the spool-shafts can always be kept in gear, so as to run evenly andv continuously, while the threads or strands of threads shall be `twisted harder, and shall be guided properly, and kept at the right tension in passing from the spools to the reel, whereby a better article of twine, 85e., can be produced than heretofore. To this end,

The invention consists in an improved arrangement of devices for holding the adjustable belt, hy which the spool-shafts are rotated, and minor improvements, to be hereafter described.

The other parts of the machine are similar tothose of machines now in common use for the same purpose.

Those parts of the machine which are not new, and upon which I lay no claim to invention, are the frame 1 A, the main shaft B, the belt b, that runs from the main shaft to a large wheel, E; the shaft F, and its pulley f, which serves to draw the twine up from the twisting-apparatus; the gearing g g, by whichthe Wheel E imparts motion to shaft F; the reel H; the belt h, and pulleys h h, by which the shaft E operates the reel; the horizontal revolving wheel K,

which supports, and carries around the spoolsI and` their shafts; the belt 7c, and pulleys la' la", by which such wheel is driven from the main shaft; and the annular plate L, around, and slightlyabove the wheel K, being fixed, by means of standards, to some part of the frame A. Neither do I lay any claim to ,the employment of a revolving vertical shaft, I, xed to, and extending upward from the centre of the wheel K, for the purpose of rotating the spools or b obbins C C C and their spindles D Dl D2 in one direction, I am while itself rotates inthe opposite direction.

well aware that all these things are old, and are to be found in different machines, with many variations in their form, combinations, and method of operation.

My invention consists in certain improvements to be used in connection with these parts, the nature and operation of which I will now particularlydescribe.

M M* M2 represent horizontal wheels, attached to the vertical spindles DD D, near their lower end, and supporting the bottoms C C G and guides N N N. These wheels or their spindles are stepped in boxes attach'edto the upper surface of the wheel K, and are carried around with it.

As they are thus carried around by the wheel Ki` and shaft I, their peripheries come in contact with a exible belt, 0, supported by standards o o, projecting up from the annular plate L, and, by this means, they, together with theirspindles on shafts D D D, and the bobbins C G O, are rotated in a direction opposite to that in which the main Wheel K moves. The belt O is attached to the standards by passing through slots provided in them, or flat staples fastened .to them for the purpose. p

The ends of the belt come together at o', and pass directly out through the standard at that point, being attached together on the outer side of said standard. By taking up or letting out the belt at this point, its tension can be perfectly adjusted so as to communi- .cate a uniform motion to the wheels M M1 M2, and,

through them, to the bobbins and shafts D D D.

In machines, for a similar purpose, in general use, a cog-gearing is usually employed to communicate motion to the bobbins, the'perimeter of each wheel M having cogs, and gearing with a ring, in the position` of lmy belt O, having cogs around its concave surface, the whole forming a kind of epicycloidal gearing; but such a gearing, after it once wears loose, cannot be adjusted again, but is henceforth utterly worthless, while in my improved device it matters not how long the machine may be in use or how much the parts may be in wear, the belt can always be adjusted so as to run the wheels with smoothness, regularity, and a much higher rate of speed. An adjustable belt for this purpose, broadly, is not new, my invention consisting in the arrangement of the parts o o for holding the same.v l

The threafds or strands, proceeding from the bobbins, are passed through a loop in the guides N N, nearly opposite t0 the upper end of the bobbins, and

`thence upward, and through another loop, at the end of the curved arm of the guide, and from that point to the side ofthe shaft D of their respective bobbins, where, after passing once around the shaft, they enter a hole, drilled for the purpose, in the shaft, and come out above the arms P I P,at the centre of the upper end of their shaft; thence they proceed upward and inward toward the upper end of shaft I, and enter a similar hole in the side of that shaft, coming out at its top, twisted into a twine, or cord, T, which passes through a guide and tension-holder, R, thence over the pulley f, and thence to the reel H.

A single thread or strand, it will be observed, comes from the top of each shaft lD D D, and enters the side of shaft I. The latter has a hole for each thread or strand drilled into its side, and thence up to itstop, the holes being entirely independent of each other, and being arranged as seen in lig. 5 at i t' fi, the red, blue, and green dots there shown, representing the several threads or strands. Each thread or strand is more thoroughly twisted by its own bobbin and'shaft D, and the. three or more strands or threads are twisted together into a single cord by the action of the shaft I, as above described. The passing of the threads or strands around the body of the shafts D D keeps the strands at their proper tension.

The guide and tension-holder It is a bifurcated piece of metal, attached, by afscrew at one "end, to the frame A, with its forked end lying over the shaft I, the twine passing up betweenv the forks in a vertical groove on their inner walls. The forks can be brought together or forced apart by means of a screw, v, so as to hold the cord more or less firmly, and theregiveit any tension that may be required.

The arms P P P, that support the upper ends of the shafts D D D, are hinged or jointed to a collar, p, attached to the shaft I, in such a manner that their outer end can be lifted up clear of the bobbinspindles,when the latter or the bobbins can be removed.

The strands upon the bobbin C are each made up of a number of smaller threads, varying from eight to forty to each strand. The strands are twisted upon a separate machine before being wound upon the bobbins.

Having thus described my invention,

What I claim as new, and desire to secure by Let@ ters Patent, is

1. The arrangement of the series of posts 0 o o around the path of the wheels M M M, when said posts are employed to support the iiexible adjustable belt O, and hold it in relation to the said wheels, as herein shown and described. 2. The guides N N when constructed with the two loops and the bent arm, and arranged, in relation to the bobbins, in the manner described and shown, and for the purpose specified.

3. The arrangement'of the belt O, wheels M M M and K, bobbins C C C, shafts D D D and I, guides N N, and varms P P P, substantially as described.
